You are advised to use the “method of kitchen paper and wet cloths” to remove the stains in the pores if the stone floor in your shower cubicle begins to have black spots.

The operating method is as follows:

◆Step 1: Clean the scope with water and a rag or mop.

◆Step 2: Cover the scope with an appropriate amount of overlapping kitchen paper (about four sheets).

◆Step 3: Spray a proper amount of household hydrogen peroxide or detergent on the kitchen paper until it soaks through the paper.

◆Step 4: Remove the kitchen paper after it was kept for 24 hours and wipe the stone surface. And then the job is done!

It is advised that you conduct a small-scale test on the corner of the stone floor to determine whether the household hydrogen peroxide or detergent you used is suitable for this kind of stone material and its stains removal effect before using it in a wider range.
